lo constructing a wall having great strength andv rigidity. This andother objects and advantages of the invention will be more fully setforth in the following description made in connection with theaccompanying drawing, in which like reference characters refer tosimilar parts throughout the several views, and in which Fig. 1 is a topplan view ofone form of my tubular piling;

Fig. 2 is a top plan view of a second form of my tubular piling;

Fig. 3 is a partial vertical view of a wall made of units such asshown-in Figs. 1 and 2;

Fig. 4 is a top plan view of-a third form; Fig. 5 is a top plan of afourth form;

Fig. 6 is a top plan view of a corner forming unit for use with unitssuch as that shown in Fig. 1, and v Fig. 'l is atop plan view of a fifthform of my pile unit. v

Referring to the drawing, the .form of my tubular piling shown in Figs.1 and 3 consists of an elongated member 6 of circular tubular crosssection having a pair of interlocking elements 1 35 extendinglongitudinally thereof and secured to diametricaliy opposite sidesthereof. Each interlocking element l has a pair of mounting anges 'laformed integrally therewith and secured to the tubular member 6 bysuitable means 40 such as welding or the-rivets 6. The two pieces eachcomprising an interlocking element 'I and a pair ofmounting flanges 1aare similar and are secured to the tubular member 6 with respectivelyopposite ends up.

The form of my pile shown in Fig. 2 is similar to the form shown inFig.l 1 with the exceptions that the tubular member 9 is of generallyoval cross section and the interlocking elements I0 are situated atpositions corresponding to the ends of the longest diameter of themember 9. are

formed integrally with, welded to or otherwise secured to the memberSand are disposed with respectively the same ends up.l In driving thisform of pile to form .a wall all of the pile units I6 are driven withthe same end up.

(ci. si-ss). f

The form of my pileI shown in Fig. 4 is similar to the formshown in Fig.3 with the exception that the interlocking elements il are situated inpositions corresponding to the ends of the shortest diameter of thetubularmember i2. 5 The form of my piling illustrated in Fig. 5 consistsof an elongated tubular member i3 of generally circular cross sectionbut having portions o`f the wall thereof at diametrically oppositepoints bent inwardly to form a pair of dia- 10 metrically locatedgenerallyrectangular grooves or recessesl extending longitudinally ofthe member I3. An interlocking element i4 extends longitudinally of eachrecess and is secured to the por'- tion of the tubular element i3forming the botl5 tom of the recess by suitable means such as weldi'ngor being formed integrally therewith. The two interlocking unitsiLofeach pile are at,- tached to the tubular element i 3 with correspondingends up. The depths of the recesses are so 20 dimensioned that facingportions ofadjoining piles in a wall formed4v thereof will abut eachother, as shown, when interlocking elements I4 of these adjoining pilesare placed in interlocking f .-relation. Thus a wan formed of such pileswm g5 have corrugated sides and Ithe interlocking elements il will beenclosed except at their ends..

To provide for producing corners or angles in a wall formed of the pileunits illustrated in Fig 5,

anv elongated tubular member I5, formed in the 30 same manner as themember i3 and being provided with interlocking elements Il in thesameway, is used. However, the interlocking elements Il of the tubularmember i5 are spaced apart circumferentially of the member I5 by' anangle 35 of `ill) degrees. as shown, or any other desired angle insteadofbeing diametrically opposite each other.

Fig. 6 shows a pile unit which is similar to the unit shown in Fig.1except that the inter- 40 locking elements .I6 thereof are welded to orformed integrally with the tubular member I1 thereof instead of having abase riveted to the tubular member. Fig. 6 also shows a pile unit foruse in forming corners or .angles in a wall 45 builtof the abovedescribed units of Fig. 6. The corner-forming unit is constructed in thesame manner as the other units with the exception that the interlockingelements I8 .thereof are spaced apart circumferentially of the tubular5o member i9 thereof by an angle of 90 degrees, asshown,.or any otherdesired angle instead of being diametrically opposite each other.

Fig. 7 shows a form of my piling identical with the' form shown in Fig.6 except that the tubular 55 PATENT *o1-Elea anlass respective singleinterlocking elements II and Il of the respective tubular members i1 andi! of Fig. 6.

If desired the interiors of the tubular members of any of the abovedescribed forms of my piling may be filled with filling material 23 suchas concrete, earth, sawdust, cinders or other material as indicated inPigs. 1, 2, 5. 8, and 7. The recesses or grooves in which theinterlocking elements of the form. of Fig. 5 are disposed may be filledwith iilling material Il as indicated in Fig. 5. Filling with material.28. as of course increases the strength of a wall made of my pile units.

In` all of the above described` forms of my piling, great strength isobtained throughthe use of tubular construetionin the same. Walk madefrom a plurality of my piling units are driven in the same manner asordinary steel sheet piling but provide substantially a double wall.

It is apparent that I have invented novel and improved steel pilinghaving a tubular form giving the same great rigidity and strength.

It will, of course, be understood that various changes may be made inthe form, detaik, arrangement and proportions oi' the parts, withoutdeparting from the scope of my invention. which. generally stated.consists in a device capable of carrying out the objects above set forthand in the novel parts and combinations of parts disclosed and deiinedin the appended claims.

What is claimed is:-

1. A tubular pile unit comprising an elongated tubular member, a portionof one side of Y said tubular member being displaced inwardly to form agroove extending longitudinally of said member, an interlocking elementattached to said tubular membery and projecting therefrom anddisposedatleastinpartinsaidgrooveaoda ysecond interlocking elementattached to said tusubstantially in abutment with each other and saidinterlocking elements will be concealed 2. A tubular pileunit comprisingan elongated tubular member having a pair of continuouscircumferentiaily spaced radially disposed longitudinal .groovestherein, interlocking elements attached to said tubular member andprojecting therefrom radially into said grooves, the interlockingelements oi the tubular member beim so arranged that when two suchmembers are connected, one interlocking element of one member willengage with one interlocking element of the other member to bring thefacing sida o! the two tubular members into contact adjacent the grooveswherein the engaging interlocking elements extend thereby concealing theenum interlocking elements and producing a multiple sealed joint betweenthe adjacent members.
